SharkTapCC 10/100/1G - When you need to know exactly what's going on

SharkTap


  • The SharkTapCC is our 'enterprise grade' model, suitable for the lab, the field, and permanent installations.

  • Provides both aggregate and carbon copy TAP ports, for convenience or byte level accuracy, as needed.

  • Power fail relay bypass, fault forwarding, and 'zero delay' repeater technology for high-availability network links

  • PoE pass-through

Frequently Asked Questions


What does 'carbon copy' mean?

  • Carbon Copy is the term I've chosen for the repeater technology used in the SharkTapCC. Basically, two ethernet PHY chips are connected back to back through the baseband RGMII bus. This produces a very small delay (about 500nS) and reproduces data at essentially a bit-for-bit level. So even industrial timing protocols can be handled by the SharkTapCC. The two carbon copy TAP ports produce the same byte accurate, zero delay copies of send and receive traffic for maximum accuracy and full bandwidth in capturing traffic.

Will the SharkTapCC "fail open"?

  • No - if the SharkTap loses power, the Network link will get a 'hard', i.e. relay, bypass. The SharkTapCC features a unique design that does not draw relay (bypass) power during normal operation, reducing the current and heat load of the SharkTap compared to older methods

Does the SharkTapCC support Power over Ethernet?

  • Yes, it does. The center tap of of the isolation transformers for each pair are connected to the corresponding center tap of the other NETWORK port. So the high speed data is blocked, but DC power is passed through. This is done for all four pairs, so all standard PoE techniques are supported. There are no settings, it just works.

Will the SharkTapCC show packets with bad FCS?

  • Yes. Everything is reproduced on the carbon copy ports, even if not valid 802.3 packets. The aggregate ports will also show bad packets, but not very short ('runt') packets. One small caveat - if both aggregate ports are active (wired and USB), only the wired TAP port will include unrouteable packets.

Can the SharkTapCC drop packets?

  • Only on the aggregate TAP ports. The SharkTap has fairly large data buffering, but if the sustained, combined data rate of send + receive data is greater than 1000Mbps, the SharkTap will not be able to duplicate all packets to the aggregate TAP port(s), so some packets can be dropped. The SharkTapCC will never drop any data on the Network ports, nor the carbon copy TAP ports.
